CAR-VENT! LATION.

SPECIFICATION forming part of Letters Patent No. 251,957, dated January3, 1882.

Application filed September 29, 1881. (No model.)

To all whom it may concern:

Be itknown that I,'JoHN SHEPHERD, a citizen of the United States ofAmerica, residing at M acon, in the countyof Macon and State ofMissouri, have invented certain new and useful Improvements inOar-Ventilators; and I do hereby declare the following to be a full,clear, and exact description of theinvention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification, and in which Figure 1 is a side view of myimprovedcooling apparatus for passenger cars, and Fig. 2 is a longitudinalsection of the same. Fig. 3 is a detail plan view, showingconducting-tubes and ventilating-orifices.

This invention relates to an improvement in air-coolin g apparatus forpassenger-cars, it being designed to collect and utilize air forcoolingthe apartments; and it consists of a flaredmouth tube connectedto a condensing fan and pipecomposed of sections, each section underacar having a supplemental fan or exhaustto supply the car with air,substantially as hereinafter more fully set forth and claimed.

In carrying out my invention I employ a condensing rotary fan, A, whosecage A may, by preference,be located upon the frontot' the locomotive asthe most eligible position to collect o'rreceivethc air. To this cage ordrum is supplied a flared-mouthed tube, B, which collects and conductsinto thecage against the fan A the airproduced by the cars in motion.The inrushing airwill revolve and cause the fan to condense the air,which is taken therefrom through sections of pipe 0 O and dischargedinto supplemental cages and in contact with supplemental fans orexhausting de- The fans D may be located within the cars,

which is the preferred way.

The locomotive-tender pipe-section is designed to be passed through thewater-chainber thereof, in order to reduce the temperature of, and thuscool, the air.

The pipe-sections under the cars are designed to be passed through iceor refrigerant chambers located thereunder to further cool the air, orrather the supply of air for each car.

Having thus fully described my invention, I claim and desire to secureby Letters Patent The combination, with the fan A, of pipe 0, andsupplemental fan D, having the pipes 01' leading'into the car,substantially as and for the purpose set forth.

7 In testimony whereof I aflix my signaturejn presence-of two witnesses.

JOHN SHEPHERD.
